- Ethiopia is building Africa's largest dam -- the Grand Ethiopian Renaissance Dam
- Situated on the Blue Nile, the dam could threaten Egypt's water supply
- Already facing water shortages, Egypt is desperate to maintain its dominance of the River Nile
This emerald ribbon is the vegetation that grows on either side of the Nile River and around its delta. It is Egypt's only fertile land -- and testament to the country's reliance on this fabled waterway.
The Nile River Basin extends to 11 African countries
, but Egypt -- one of the oldest civilizations in the world -- has controlled the river and used the lion's share of its waters for millennia.
That could be about to change.
Ethiopia's very big dam
The Blue Nile River is the Nile's largest tributary and supplies about 85% of the water entering Egypt. Ethiopia is building its $5 billion Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile, near the border with Sudan. When completed, it will be the largest dam in Africa, generating around 6,000 megawatts of electricity for both domestic use and export
Ethiopia's ambitious project is designed to help lift its fast-growing population out of poverty. But the new dam also puts management of the flow of the Blue Nile in Ethiopia's hands -- and that has sparked a power shift in the region.
For the Egyptians, the Nile is, literally, a lifeline. The vast majority
of the country's 97 million
people live along its banks.
